Secondary Organic Aerosols (SOAs) are a significant component of atmospheric particulate matter, formed through the oxidation of volatile organic compounds (VOCs) in the atmosphere. They play a crucial role in air quality, climate change, and human health by influencing atmospheric chemistry, cloud formation, and the Earth's radiation balance.

Oxidation of volatile organic compounds

Volatile Organic Compounds (VOCs) are organic chemicals that easily evaporate at room temperature and can significantly impact indoor and outdoor air quality. They originate from various sources, including industrial processes, vehicle emissions, and household products, and are associated with health risks and environmental issues like smog formation.

Volatile Organic Compounds

Air quality refers to the condition of the air within our surroundings, which affects human health and the environment. It is determined by the presence and concentration of pollutants and is influenced by natural and anthropogenic sources, weather conditions, and geographic factors.

Air Quality

Climate change refers to significant, long-term changes in the global climate, largely driven by human activities such as burning fossil fuels, deforestation, and industrial processes. It results in global warming, extreme weather events, sea level rise, and disruptions to ecosystems, affecting biodiversity and human societies worldwide.

Climate Change

Human health is a multifaceted state of physical, mental, and social well-being, not merely the absence of disease or infirmity. It is influenced by a complex interplay of genetic, environmental, lifestyle, and healthcare factors that can affect an individual's ability to lead a fulfilling life.

Human Health

Atmospheric chemistry is the study of the chemical composition of the Earth's atmosphere and the reactions and interactions that occur among atmospheric components. It plays a crucial role in understanding climate change, air pollution, and the depletion of the ozone layer, influencing both environmental policy and public health.

Atmospheric Chemistry

Cloud formation is the process by which water vapor in the atmosphere cools and condenses into visible water droplets or ice crystals, forming clouds. This process is driven by various atmospheric conditions, including temperature, pressure, and humidity, and plays a critical role in weather patterns and the Earth's climate system.
